You are so lucky to be able to see these in the wild. It is to bad cp's in the wild are slowly disapering from poachers. If I ever saw one all I would take home is a picture and a memory. Nice photos. Where abouts is this? And was it in a bog?
I'd rather not say where they were specifically, but they were growing on an alvar, which is a flat rocky area made up of limestone. They're very wet like a bog, but they're alkaline rather than acidic.
Ask not what sundew can dew for you but what you can dew for sundew.
You are right, Jeff. P.villosa does not grow as far south as P.vulgaris. The father south the more alpine those stations are. Unlike P.vulgaris, P.villosa needs slow growing Sphagnum to survive and has adapted to a very short vegetation period. But it is somewhat surprising that P.vulgaris is more successful in arctic regions (<10°C in July) like northern Canada, Greenland and Iceland. This is because it is more of a generalist and grows well in wet seeps on mineralic substrate. But both species live rather in the boreal zone than in the subpolar zone. Look at those maps: P. vulgaris (Den virtuella Floran) P. villosa (Den virtuella Floran)
for me P.vulgarissubsp vulgaris is not only a boreal specie, see here the boreal zone in europe zone boreale Here in europe we find them in plain or mountain also, in a lot of substrate: peat , calcareous , sphagnum ,on rock ,etc. In plain , like here to LE MANS ,they are in strong regression due to the climatic change.
sorry for the confusion. There are many climate zone definitions. With the boreal zone I ment the circumboreal zone. Or for Canada look at this simple map or more detailed map (or even the Köppen Climate Classification) and lets include the subpolar zone into the boreal zone, because I wanted to point out the contrast to the arctic zone. Here, in the boreal zone, you'll find suitable habitat for Pinguicula and other northern CPs more easily. Sure, P.vulgaris has a much wider ecological amplitude than the specialised P.villosa, if you look at it from the South. It approximately includes those USDA hardiness zones: P.vulgaris 1 - 5 (for N-America excluding P.macroceras), - 8 (like Le Mans for Europe or even 9 for the Atlas Mountains). P.villosa 2 - 4 (1, too, for Sibiria and Alaska) It is somewhat surprising that P.vulgaris does not move as far south as it does in Europe. This shows how limited some climate or hardiness maps can be. The Mediterranean just can't be compared to Florida, but California (where P.macroceras lives) can. Some sites like cold groundwater seeps may also have a much cooler microclimate, very different to the large scale zones.
